FLANGES FOR WAVEGUIDES –
Part 4: Relevant specifications for flanges for circular waveguides

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60154-4 has been prepared by subcommittee 46F: RF and
microwave passive components, of IEC technical committee TC 46: Cables, wires,
waveguides, RF connectors, RF and microwave passive components and accessories.
This second edition cancels and replaces the first edition published in 1969. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) revise the estimation for return loss at connection interface of waveguides;
b) add two type of waveguide flange for high frequency application, i.e. over 50 GHz;
c) expand the operation frequency range up to 3,3 THz;
d) rename the frequency band over R1200, i.e. R1.2K.

FLANGES FOR WAVEGUIDES –
Part 4: Relevant specifications for flanges for circular waveguides

1 Scope
This part of IEC 60154-4 specifies the dimensions of flanges for circular waveguides for use
in electronic equipment.
It covers requirements for flanges drilled before or after mounting on waveguides.
The aim of this document is to specify for waveguide flanges the mechanical requirements
necessary to ensure compatibility and, as far as practicable, interchangeability as well as to
ensure adequate electrical performance.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their
content constitutes requirements of this document. For dated references, only the edition
cited applies. For undated references, the latest edition of the referenced document (including
any amendments) applies.

3 Terms and definitions
No terms and definitions are listed in this document.
ISO and IEC maintain terminological databases for use in standardization at the following
addresses:
• IEC Electropedia: available at http://www.electropedia.org/
• ISO Online browsing platform: available at http://www.iso.org/obp
4 General
4.1 Standardized types
The series of flanges for circular waveguides covered by this document is shown in
Figures B.1 to B.4.
Dimensions of flanges for preferred waveguide sizes are given in Table A.1.
Dimensions of flanges for both intermediate and preferred waveguide sizes are given in
Table B.1.
4.2 Type designation
For the standardized types of flanges, the type designation comprises:
• the code: 60154 IEC;
– 6 – IEC 60154-4:2017 © IEC 2017
• a dash;
• a letter relating to the basic construction of the flange, viz.:
– P = pressurizable
– U = unpressurizable
• a letter for the type according to the drawing;
• the letter and number of the waveguide for which the flange is designed.
EXAMPLE 60154 IEC – PJC 18 denotes a pressurizable type flange for circular waveguide 60153 IEC – C 18.
